De Microsoft implementatie van callback is niet compatibel met RFC 1570 . Vanwege het grote marktaandeel van de Microsoft inbelnetwerkclient heeft Cisco echter het Microsoft Callback (MSCB) Control Protocol in Cisco IOS® Software release 11.3(2)T en hoger geïmplementeerd.
Zorg er voordat u deze configuratie probeert voor dat u aan deze vereisten voldoet:
Configureer de netwerktoegangsserver (NAS) met het oog op aanvaarding van analoge oproepen van de client. Terugbellen is een extra functie voor inbellen via de modem. Controleer daarom of dit aspect correct functioneert. Dit kan u helpen bij het oplossen van problemen.
Het T1/E1-circuit moet in staat zijn om uit te schakelen. Neem contact op met uw telefoonbedrijf (Telco) om dit te controleren.
De informatie in dit document is gebaseerd op Cisco IOS-softwarerelease 11.3(2)T en latere versies.
Dit scenario werd getest op een PC met het netwerk van de wijzerplaat van Windows.
De informatie in dit document is gebaseerd op apparaten in een specifieke laboratoriumomgeving. Alle apparaten die in dit document worden beschreven, hadden een opgeschoonde (standaard)configuratie. Als u in een levend netwerk werkt, zorg er dan voor dat u de potentiële impact van om het even welke opdracht begrijpt alvorens het te gebruiken.
Zie de Cisco Technical Tips Convention voor meer informatie over documentconventies.
Terugbellen voert in deze volgorde uit:
Een PC-gebruiker (client) sluit aan op de Cisco-toegangsserver.
Callback-proces wordt besproken in de LCP-fase (Point-to-Point Protocol) van de Link Control Protocol (LCP).
PPP authenticatie wordt uitgevoerd.
De Cisco IOS software bevestigt callback regels voor deze gebruiker of lijn en sluit de aanroep voor callback af.
De Cisco toegangsserver voert de client aan.
Er zijn vier soorten MSCB:
Geen terugbellen.
Door de gebruiker ingesteld callback nummer.
Door server opgegeven (vooraf ingesteld) callback number.
Lijst van vooraf ingesteld callback nummer.
De standaardconfiguratie is geen callback (optie 1). Opties 2 of 3 kunnen worden ingesteld:
Lokaal (indien geen AAA-server gebruikt wordt).
In het TACACS+ of RADIUS-gebruikersprofiel (als AAA wordt gebruikt).
Als optie 2 is ingesteld, wordt de gebruiker gevraagd zijn callback-nummer in te voeren. Als optie 3 is ingesteld, biedt de melding slechts één keuze, namelijk het door de beheerder bepaalde nummer.
Cisco implementeert alleen de callback serverfunctionaliteit van MSCB en niet de callback client functionaliteit. Dit betekent dat een Cisco-router alleen als MSCB-server en niet als MSCB-client kan worden gebruikt. Daarnaast vereist de Cisco-implementatie van MSCB dat de verificatie op de client wordt uitgevoerd.
Deze sectie bevat informatie over het configureren van de functies die in dit document worden beschreven.
Om MSCB in te schakelen moet u de terugbellen van ppp toestaan opdracht onder de ontvangende interface (bijvoorbeeld, groep-async). Bovendien, omdat verificatie vereist is, moet u Wachtwoord Verificatie Protocol (PAP) of Challenge Handshake Authentication Protocol (CHAP) inschakelen:
ppp authentication chap pap
Twee chatscripts worden automatisch gemaakt. Dit zijn de openhartige en callback chat-scripts:
chat-script offhook "" "ATH1" OK chat-script callback ABORT ERROR ABORT BUSY "" "ATZ" OK "ATDT \T" TIMEOUT60 CONNECT \c
De chat-scripts worden ook automatisch toegepast op de gebruikte regels:
line 1 24 script modem-off-hook offhook script callback callback
Een gebruiker moet toestemming hebben om terug te bellen. U kunt dit lokaal configureren op NAS of op de externe AAA-server (RADIUS of TACACS+), op basis van de locatie waar de gebruikersnaam en de wachtwoordinformatie is opgeslagen.
Dit is een lokale configuratie voor een gebruiker die wordt teruggeroepen op 5551212:
username callmeback callback-dialstring 5551212 password cisco
Deze lokale configuratie is van toepassing op gebruikers die hun eigen callback-nummer mogen instellen:
username callmeback callback-dialstring "" password cisco
Het netwerk in dit document is als volgt opgebouwd:

Voor Windows 95 en 98 PC's is er geen speciale client-side configuratie voor callback. De toegangsserver verwerkt de callback eigenschappen van de verbinding. De Windows 95 of 98 PC toont een "wachtend op callback"bericht om aan te geven dat een callback bezig is.
Configureer deze platforms om callback aan te vragen. Volg deze stappen om ze te configureren:
Kies Start > Programma's > Accessoires > Communicatie > Netwerkverbindingen en inbelverbindingen.
Kies Geavanceerd > Voorkeuren inbelen in het menu.
Klik op het tabblad Terugbellen om toegang te krijgen tot het menu met terugbelfuncties zoals in afbeelding 1.
Configureer de callback opties zoals nodig:
Als u de callback functie niet wilt gebruiken, klikt u op de knop Geen terugbellen.
Om te worden gevraagd wat te doen wanneer een server terugbellen aanbiedt, klikt u op Vraag me tijdens het bellen wanneer de knop Server aanbiedt.
Om de callback aanbiedingen automatisch te accepteren, klikt u op het altijd bellen: Terug bij het nummer of de nummers onder de knop en vervolgens selecteert u het te gebruiken apparaat in de lijst.
Als u het telefoonnummer wilt wijzigen, selecteert u het apparaat en klikt u op de knop Bewerken. Voer het nummer in het veld Telefoonnummer in zoals in afbeelding 1, en klik vervolgens op OK in het dialoogvenster Bel me terug.
Klik op het veld Telefoonnummer en voer het nummer in in het dialoogvenster Bel me terug (weergegeven in afbeelding 1). Klik op OK wanneer u klaar bent.
Als u klaar bent, klikt u op OK in het dialoogvenster Voorkeuren inbelen.

Bepaalde opdrachten met show worden ondersteund door de tool Output Interpreter (alleen voor geregistreerde klanten). Hiermee kunt u een analyse van de output van opdrachten met show genereren.
toon actief—geeft informatie weer over huidige inkomende en uitgaande ISDN-oproepen. Gebruik deze opdracht om te controleren of de callback is voltooid. Als callback succesvol is, toont isdn actief de vraag als uitgaande op de callback server.
toon gebruikers-toont informatie over de actieve lijnen op de router. U kunt ook de opdracht Show caller gebruiken als uw versie van Cisco IOS-software deze ondersteunt.
tonen dialer-toont algemene diagnostische informatie voor interfaces die voor Dial-on-Demand Routing (DDR) zijn geconfigureerd.
Deze sectie bevat informatie waarmee u problemen met de configuratie kunt oplossen.
Opmerking: Voordat u debug-opdrachten afgeeft, raadpleegt u Belangrijke informatie over debug-opdrachten.
Voor meer informatie over het zuiveren van opdrachten, zie de Referentie van de Opdracht van Cisco IOS release 12.0 debug.
debug van verificatie door middel van detectie - geeft informatie weer over AAA-verificatie.
debug a autorisatie—geeft informatie weer over AAA autorisatie.
debug callback - displays wanneer de router een modem en een chatscript gebruikt om terug te bellen op een eindlijn.
debug modem - stelt u in staat om modemlijnactiviteit op een toegangsserver te observeren.
debug ppp [ pakje | onderhandelingen | fout | authenticatie— geeft informatie over verkeer en uitwisselingen weer in een internetwerk dat PPP toepast.
pakket - toont PPP pakketten die worden verzonden en ontvangen. (Deze opdracht geeft pakjes op een laag niveau weer.)
onderhandeling-toont PPP pakketten die tijdens PPP opstarten worden verzonden, wanneer PPP opties worden overeengekomen.
fout-toont protocolfouten en foutstatistieken die bij de PPP-verbindingsonderhandeling en -handeling worden gebruikt.
Verificatie—hiermee worden verificatieprotocol-berichten weergegeven, waaronder CHAP- en PAP-uitwisselingen.
debug chat-toont de handdruk tussen de toegangsserver en de interne modem terwijl de modem is opgedragen om uit te bellen. Een chat-script is een set string paren die de handdruk definiëren tussen data terminal apparatuur (DTE) en data communicatie apparatuur (DCE) apparaten.
debug ISDN Q931: geeft de installatie-en uitsplitsingsberichten en debugs van ISDN Q.931 (D-kanaal) weer. In dit scenario wordt de modemoproep gedragen als een service aan toonder via het openbare telefoonnetwerk (PSTN).
debug modem csm-stelt u in staat om problemen met Call Switching Module (CSM) op routers met interne digitale modems te oplossen. Met deze opdracht, kunt u de volledige reeks van het overschakelen van inkomende en uitgaande oproepen overtrekken.
